The Wedding Singer is set in 1985, but it might as well have just been set in “The 80s” in big block letters, scare quotes preserved. As represented in that late ‘90s Adam Sandler-starring hit, the ’80s were more of a simultaneous event than a brimming block of time that bore its own shifts and specifics as it rolled on. In the 1985 of the Sandlerverse, New Order was as popular as Nightmare on Elm Street and Billy Idol held simultaneous relevance to “Billie Jean”-era Michael Jackson. Any sign of a previous decade having existed before the ’80s is absent. Much of cinema’s millennial nostalgia for the ‘80s followed the lead of The Wedding Singer. From American Psycho to Hot Tub Time Machine, the ’80s of the ’00s have not been so much a part of history as they are an “idea” having to do with greed, excess, frivolous pop culture, and easy cracks at anachronistic fashion. But somewhere down the line, at some point between La Roux and The Americans, we started to take the ‘80s seriously.
